CREAM-SEPARATOR AND CHURNV.

SPECIFICATION forming part of Letters IPatent No. 705,361, dated. July22, 1902.

Application led May 24, 1902. Serial No. 108,834. (No model.) l

To all w/wm/ it may concer-71,: y

Beit known that I, JOSEPH KLEIN, a citizen of the United States,residing at Cass Cit-y, in the county of Tuscola and State of Michigan,have invented new and useful Improvements in Cream-Separators andChurns, of which the following is a specification. l

My invention relates to improvements in churns; and it consists in thepeculiar and advantageous cream separator and churn hereinafterdescribed, and particularly pointed out in the claims appended.

In the accompanying drawings, yFigure lis a vertical section of myimproved cream-separator and churn. Fig. 2 is a detail section taken inthe plane indicated by the broken line 2 2 of Fig. 1 and illustratingthe upper dasher, which serves the additional function of drawingatmospheric air into the can; and Fig. 3 is a detail section taken inthe plane indicated by the broken line 3 3 of Fig. l and illustratingone of the lower dashers, which serve, in addition to agitating the`rnilk and cream, to draw air through the hollow dashershaft into thesame. Y

Similar letters of reference designate corresponding parts in all of theviews of the drawings, referring to which- A is the main frame of mycream-separator and churn, which preferably comprises a base a,corner-uprights b, and upper horizontal bars c and is by preferencesurmounted by a top B, having a leaf d, hinged in such manner as topermit of it being raised and lowered, and C is the can. This can isarranged on the base a of the frame A and is preferably provided with adraw-off cock e and a sight-glass f. It is also providedwith a removablecover D, which is preferably concavo-convex in form and arranged withits convex side down and is provided with a cen- -horizontal disk j andvertical curvilinear blades 7a', Figs. l and 2, arranged on said disk.'

It is also provided at intermediate points of its height with aperturesk, Z, and m and adjacent tothe apertures l and m with dashers G H,respectively. These dashers respecl i is a standard connected to andrising from the leaf d of cover B; J, a vertically-y disposed postflxedly connected to said sta'ridfV54 ard and having upper and lowerportions of,4r

a lateral journal r; K, a beveled idler-pinion mounted on the uppercircular portion of post J and secured in position by a collar 3 andset-screw t; L, a shaft having a lower end portion u of angular form incross-section removably secured in a corresponding socket fu in theupper end of the dasher-shaft E by a set-screw w and also having abeveled pinion a: at its upper end and a socket 'y in said end receivingthe lower end portion of post J, and M a miter-gear mounted on thejournal r and in termeshed with the pinions K and a; and provided with acrank e. As before stated, the pinion K is an idler-pinion, its solepurpose being to prevent lateral play of the gear M, with a view ofholding said gear at all times in proper engagement with the pinion :vofthe shaft L.

It will be appreciated from the foregoing that when the set-screw w isloosen ed the leaf d may be swung upwardly toward the right tocarry'shaft L out of engagement with the flasher-shaft E; also, thatwhen the leaf and the parts carried thereby are in the raised positionthe cover D may be readily removed from can C and as readil)7 replacedthereon. In using the apparatus the milk or cream is preferably pouredin the can C while the cover D is removed, and the cover is thenreplaced and the parts returned to and secured in the positions shown inFig. 1,- when the apparatus will be ready for operation.

When the apparatusV is used las a creamseparator and the shaft E isrotated, the dashers F, G, and H will serve to thoroughly agitato themilk. The dasher F will also serve 65 Y circular form in cross-sectionand also having A IOO to draw atmospheric air into the can through thespace g, while the dashers G H will perform the additional function ofdrawing such air into the shaft through the apertures 7c and downthrough the shaft and the apertures l m into the milk, with the resultthat the milk will be aerated and cooled and the separation of the creammaterially accelerated. Then the apparatus is used as a churn, the creamwill be agitated and aerated and cooled, as stated, and in consequencebutter will be quickly produced.

When the shaft L is disconnected from the dasher-shaft E and the leaf dis swung upwardly toward the right,the flasher-sh aft may obviously bereadily removed from the can with a View of facilitating cleaning ofthecan, dasher-shaft, and can-cover.

I have entered into a detailed description of the construction andrelative arrangement of parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and arrangement of parts,as such changes or modifications maybe made in practice as fairly fallwithin the scope of my claims` Having described my invention, What Iclaim, and desire to secure b v Letters Patent, is

l. In an apparatus for the purpose described, the combination of a canhaving a cover provided with an opening for the admission of air, anupright, hollow shaft arranged in the can, and having an openingadjacent to the cover for the admission of air and an opening, belowsaid inlet-opening, for the exit of air, a dasher arranged on said shaftabove the air-inlet opening thereof, and comprising a at horizontaldisk, and curvilinear blades on the upper side of the same, and a dasherarranged on the shaft adjacent to the air-exit opening, and comprising aHat, horizontal disk, and curvilinear blades on the under side of thesame.

2. In an apparatus for the purpose described, the combination of a canhaving a cover provided with an opening for the admission of air, anupright hollow shaft arranged in the can, and having an opening adjacentto the cover for the admission of air, and an opening, below saidinlet-opening, for the exit of air, a combined dasher and airsuctiondevice arranged on said shaft above the air-inlet opening thereof andbelow the air-inlet opening in the can-cover, and a combined dasher andair-suction device arranged on the shaft adjacent to the air-exitopening thereof.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOSEPH KLEIN.
